F15.28 Zero-frequency operation threshold 0.00
F00.06
0.00Hz
Zero-frequency hysteresis
F15.28 and F15.29 are used to set the
zero-frequency operation output control function,
please see the right figure.
F15.30 FDT1 detection mode 0,1

0: Detect according to the reference frequency.
1: Detect according to the output frequency.
F15.31 FDT1 level 0.00
F00.06
50.00Hz
The indicating signal can be output if the setting
frequency F15.30 is higher than certain frequency
(F15.31), and becomes disabled when the setting
frequency is lower than certain frequency of
FDT1 level (F15.31 - F15.32). Please refer to FL
of the right figure.
0: Detect according to the reference frequency.
1: Detect according to the output frequency.
F15.35 FDT2 lag 0.00
F00.06
1.00Hz
Refer to parameters F15.31 and F15.32.
